I'm not sure if this will work, but I have a 42 slot Quantum M1800 (two
M1500s stacked)
tape library with a 64 slot Autochanger. I have an snode managing this,
running 7.2.2 on Linux.
I'll bite the bullet on the 64-slot license if there's no way around it,
but I'd really like to get this to
work with a 40 slot license to save cost. That way we could upgrade a 32
slot license we no longer
need to a 40 slot for the Quantum and then upgrade the 64-slot license
to a 128 slot license for a new library.
This would be a big savings, I don't care about giving up two slots.
Those last two slots are fixed slots that
can be used for data cartridges, but are usually reserved for cleaning
cartridges, and I don't let NW do the cleaning.
To test, I added a 40 slot temp license (exp date = Mar 15, 2008),
removed the permanent license, stopped and restarted everything.
When I try to mount tapes, NW complains with the following:
Jukebox 'rd=snode:M1800' failed: The jukebox 'rd=snode:M1800' is not
properly licensed. Make sure
the jukebox is properly enabled and authorized.
A soon as I re-added the 64-slot license it started working properly -
no restart required. Well, this didn't surprise me.
The jukebox config lists the physical slots as 1-42, but I do have
available slots listed at 1-40 because when I originally
configured the library I told NW to reserve slots 41-42 for cleaning. I
later switched to doing cleaning on the library.
I tried clearing out the 'Cleaning slots' field, but that didn't resolve
this issue. NW still lists:
41 Cleaning Tape (17 us
42 Cleaning Tape (29 us
in the mount window (nwadmin). If I run 'changers -ldv' on the snode,
it reports:
[email protected]:Vendor <M4 DATA>, Product <MagFile>, Revision <12.0>
1 MT Element(s) starting at address 32
40 ST Element(s) starting at address 192
4 DT Element(s) starting at address 128
I've not tried removing the jukebox and reconfiguring it with nsrjb. I
think when I originally configured
it, I hadn't first enabled Cleaning on the library for those two slots.
1. Should I try removing the jukebox and reconfiguring it now that the
library is set to see those two slots
as cleaning slots? Might that work?
2. How about if I run nsradmin and then change the physical slots from
1-42 to 1-40? I've never tried that,
but I don't think it's possible in nwadmin. It does appear editable in
nsradmin, though?
3. If that won't work, could I shut down NW on the primary sever and
snode and then manually edit
the corresponding res file
(/nsr/res/nsrdb/06/001a00fb000000000000000044d20f130a5aeb07)?
This appears to be an ASCII file. Then restart everything? Would that be
a quick way to test it?
Don't want to risk corrupting anything so just asking first.
Would appreciate any suggestions.
